[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The cylinder is equipped with a locking mechanism, which makes it easy to fix the cylinder head to the cylinder barrel. When disassembly is required, the control board controls the first electric push rod to start, which causes the push plate fixedly connected to the first electric push rod to push the first magnetic block to move towards the baffle, which in turn pushes the baffle fixedly connected to the second magnetic block to move. When the surface of the second magnetic block is close to the surface of the first magnetic block and is flush with the surface of the locking block, the first spring releases the stored elastic potential energy, thereby pushing the locking block to move and slide out of the sliding groove, thus separating the cylinder head from the cylinder barrel. Compared with the current cylinder head and cylinder barrel connection method, this device makes it easier for operators to disassemble the cylinder barrel and cylinder head.

[0017] 2. After removing the cylinder head and cylinder, the main control board starts the drive motor, causing the drive rod, which is fixedly connected to the output end of the drive motor, to rotate. Through the threaded transmission between the trapezoidal block and the threaded part on the drive rod, the trapezoidal block slides on the drive rod. Through the cooperation between the trapezoidal block and the ejector block, the ejector block slides out of the first sliding hole, so that the ejector block that has slid out of the first sliding hole presses against the main sealing sleeve. The operator can remove the main sealing sleeve inside the cylinder by pulling out the piston rod. Because a drive mechanism is provided, the operator can pull out the main sealing sleeve at the same time as pulling out the piston rod, which makes it easier for the operator to disassemble the main sealing sleeve inside the cylinder.

[0018] 3. After the piston rod is removed from the cylinder, the main control board controls the extension of the second electric push rod, causing the crossbar fixedly connected to the second electric push rod to move towards the connector. This causes the mating block on the crossbar to also move towards the connector. As the mating block moves towards the connector, the wedge block slides into the second sliding hole through the engagement of the mating block and the wedge block. The extension of the second electric push rod stops when the mating block passes the second sliding hole and approaches the surface of the second electric push rod. The operator can then pull the second connector out in the opposite direction of the piston rod to disassemble the first and second connectors. After removing the second connector from the first connector, the nut can be unscrewed from the second connector to remove the piston sleeve and buffer sleeve. Then, the anti-fouling ring, anti-wear ring, and sealing ring can be removed from the piston sleeve. Compared to the current disassembly of hydraulic cylinders, this hydraulic cylinder greatly simplifies the disassembly process for operators, thereby reducing the difficulty of disassembly to a certain extent.

[0032] Reference Figures 1 to 8 The present invention provides a further description of an embodiment of an easily detachable main top hydraulic cylinder.

[0033] A detachable main hydraulic cylinder includes a cylinder barrel 1, one end of which communicates with the outside. A liquid inlet 2 communicating with the interior is formed on the surface of the cylinder barrel 1, away from the end of the cylinder barrel 1 communicating with the outside. A liquid outlet 3 communicating with the interior is formed on the surface of the cylinder barrel 1, near the end of the cylinder barrel 1 communicating with the outside. An internal groove 4 is provided at the end of the cylinder barrel 1 near the liquid outlet 3. A sliding groove 5 is provided on the surface of the cylinder barrel 1. A placement groove 6 is formed on the surface of the cylinder barrel 1, within which a control main board 7 is disposed. The control main board 7 is detachably and fixedly connected to the cylinder barrel 1. An annular protrusion 8 is provided on the inner surface of the end of the cylinder barrel 1 near the liquid outlet 3. The cylinder 1 is equipped with a locking mechanism, which is electrically connected to the control main board 7. The cylinder 1 is connected to the cylinder head 9 through the locking mechanism. The cylinder head 9 has an insertion hole 10 on its side. The cylinder 1 is equipped with a main sealing sleeve 11, which is slidably connected to a piston rod 12. A connecting ring 13 is provided at one end of the piston rod 12 that extends out of the cylinder 1. The connecting ring 13 is fixedly connected to the piston rod 12. The piston rod 12 is equipped with an inner groove 14. The piston rod 12 is equipped with a drive mechanism, which is electrically connected to the control main board 7. The piston rod 12 is equipped with a tail mechanism at one end inside the cylinder 1, which is electrically connected to the control main board 7.

[0034] Preferably, the engaging mechanism includes a telescopic component and an engaging component. The telescopic component is disposed in the built-in slot 4 and is electrically connected to the control main board 7. The engaging component cooperates with the telescopic component.

[0035] Preferably, the telescopic assembly includes a first electric push rod 15, a push plate 16, and a first magnetic block 17. The first electric push rod 15 is disposed in the built-in groove 4 and is fixedly connected to the cylinder 1. The first electric push rod 15 is electrically connected to the control main board 7. The push plate 16 is fixedly connected to the first electric push rod 15 and is slidably connected to the built-in groove 4. The surface of the push plate 16 away from the first electric push rod 15 is provided with the first magnetic block 17, and the first magnetic block 17 is fixedly connected to the push plate 16.

[0036] Preferably, the telescopic assembly includes a locking block 18, a first spring 19, a baffle 20, and a second magnet 21. The locking block 18 is inserted into the sliding groove 5 through the insertion hole 10. The locking block 18 is slidably connected to the insertion hole 10 and the sliding groove 5 respectively. The surface of the locking block 18 is provided with a locking groove 22. The first spring 19 is disposed in the sliding groove 5, and one end of the first spring 19 is fixedly connected to the cylinder 1. The baffle 20 and the second magnet 21 are both disposed in the locking groove 22. The baffle 20 is slidably connected to the locking groove 22. The second magnet 21 is disposed on the surface of the baffle 20 near the first magnet 17. The second magnet 21 and the first magnet 17 attract each other.

[0037] When the cylinder needs to be disassembled, the main control board 7 controls the first electric push rod 15 to start, so that the push plate 16, which is fixedly connected to the first electric push rod 15, pushes the first magnetic block 17 to move towards the baffle 20, and pushes the baffle 20, which is fixedly connected to the second magnetic block 21, to move. When the surface of the second magnetic block 21 approaches the first magnetic block 17 and is flush with the surface of the locking block 18, the first spring 19 releases the stored elastic potential energy, thereby pushing the locking block 18 to move and slide out of the sliding groove 5, thereby causing the cylinder head 9 to separate from the cylinder barrel 1.

[0038] When it is necessary to fix the cylinder head 9 to the cylinder barrel 1, the locking block 18 is inserted into the sliding groove 5 through the insertion hole 10 on the cylinder head 9. During the process of the locking block 18 being inserted into the sliding groove 5, the first spring 19 stores elastic potential energy to facilitate the subsequent separation of the cylinder head 9 from the cylinder barrel 1. During the movement of the locking block 18, when the first magnetic block 17 and the second magnetic block 21 correspond, the second magnetic block 21 attracts the first magnetic block 17, causing the first magnetic block 17 to move towards the inner groove 4. At the same time, the main board 7 controls the first electric push rod 15 to retract, so that the first magnetic block 17, which is attracted to the second magnetic block 21, is inserted into the inner groove 4. At this time, the cylinder head 9 is fixed to the cylinder barrel 1.

[0039] The cylinder is equipped with a locking mechanism, which makes it easy to fix the cylinder head 9 to the cylinder barrel 1. When disassembly is required, it is also easy to remove the cylinder head 9 from the cylinder barrel 1. Compared with the current connection method of cylinder head 9 and cylinder barrel 1, this device makes it easier for operators to disassemble cylinder barrel 1 and cylinder head 9.

[0040] Preferably, the drive mechanism includes a drive component and a pop-out component. The drive component is disposed on the piston rod 12 and is electrically connected to the control main board 7. A first sliding hole 23 is provided on the surface of the piston rod 12. The first sliding hole 23 communicates with the inner groove 14 and is disposed opposite to the annular protrusion 8. The pop-out component is disposed in the first sliding hole 23 and cooperates with the drive component.

[0041] Preferably, the drive assembly includes a motor cover 24, a drive motor 25, a drive rod 26, a trapezoidal block 27, and a fixed rod 28. The motor cover 24 is disposed on the surface of the piston rod 12 where the connecting ring 13 is provided, and the motor cover 24 is fixedly connected to the piston rod 12. The drive motor 25 is disposed inside the motor cover 24 and is electrically connected to the control main board 7. The drive rod 26 and the fixed rod 28 are both disposed in the inner groove 14. The end of the drive rod 26 near the drive motor 25 is fixedly connected to the output end of the drive motor 25, and the end of the drive rod 26 away from the drive motor 25 is rotatably connected to the piston rod 12. The end of the fixed rod 28 is fixedly connected to the piston rod 12. The surface of the end of the drive rod 26 away from the drive motor 25 is provided with a threaded portion 29. The trapezoidal block 27 is disposed on the drive rod 26, and the trapezoidal block 27 is threadedly connected to the threaded portion 29 on the drive rod 26. The trapezoidal block 27 is slidably connected to the fixed rod 28.

[0042] Preferably, the pop-out component includes a pop-out block 30, a connecting block 31, and a second spring 32. The connecting block 31 is disposed on the surface of the pop-out block 30 and is fixedly connected to the pop-out block 30. The pop-out block 30 is slidably connected to the first sliding hole 23 and cooperates with the trapezoidal block 27. The second spring 32 is disposed in the first sliding hole 23, and the ends of the second spring 32 are fixedly connected to the connecting block 31 and the piston rod 12, respectively.

[0043] After removing the cylinder head 9 and cylinder 1, the control board 7 controls the drive motor 25 to start, causing the drive rod 26, which is fixedly connected to the output end of the drive motor 25, to rotate. Through the threaded transmission of the trapezoidal block 27 and the threaded part 29 on the drive rod 26, the trapezoidal block 27 slides on the drive rod 26. Through the cooperation of the trapezoidal block 27 and the pop-out block 30, the pop-out block 30 partially slides out of the first sliding hole 23, so that the pop-out block 30 sliding out of the first sliding hole 23 abuts against the main sealing sleeve 11. The operator can remove the main sealing sleeve 11 inside the cylinder 1 by pulling out the piston rod 12. With the drive mechanism, the operator can pull out the main sealing sleeve 11 at the same time as pulling out the piston rod 12, which makes it easier for the operator to disassemble the main sealing sleeve 11 inside the cylinder 1.

[0044] Example 2:

[0045] Based on Embodiment 1, the tail mechanism includes a connecting component and a sealing component. The connecting component is located at one end of the piston rod 12 inside the cylinder 1 and is fixedly connected to the piston rod 12. The sealing component is located on the connecting component and is electrically connected to the control main board 7.

[0046] Preferably, the connecting assembly includes a first connector 33, a sliding rod 34, a circular plate 35, a return spring 36, and a wedge block 37. The first connector 33 is fixedly connected to one end of the piston rod 12 that extends into the cylinder 1. A through groove 38 is provided on the end face of the first connector 33 away from the piston rod 12. A second sliding hole 39 is provided on the side of the first connector 33, and the second sliding hole 39 communicates with the through groove 38. One end of the sliding rod 34 near the through groove 38 is fixedly connected to the wedge block 37. The wedge block 37 is slidably connected to the second sliding hole 39. One end of the sliding rod 34 away from the through groove 38 is fixedly connected to the circular plate 35. The return spring 36 is sleeved on the sliding rod 34.

[0047] Preferably, the sealing assembly includes a second connector 40, a second electric push rod 41, a crossbar 42, a mating block 43, a semi-circular block 44, a buffer sleeve 45, a piston sleeve 46, a contamination ring 47, an anti-wear ring 48, a sealing ring 49, and a nut 50. The second connector 40 has an internal groove 51 at its end near the first connector 33. The second electric push rod 41 is disposed within the internal groove 51 and is fixedly connected to the second connector 40. The second connector 40 is electrically connected to the control main board 7. The crossbar 42 is disposed within a through groove 38, and the end of the crossbar 42 near the second electric push rod 41 is fixedly connected to the second electric push rod 41. Next, the end of the crossbar 42 away from the second electric push rod 41 is fixedly connected to the semicircular block 44. The mating block 43 is set on the crossbar 42 and is slidably connected to the crossbar 42. Both the semicircular block 44 and the mating block 43 are mated with the wedge block 37. The end of the second connector 40 away from the piston rod 12 is also provided with a threaded part 29. The buffer sleeve 45 is set on the second connector 40. The piston sleeve 46 is set on the second connector 40. The anti-fouling ring 47, the anti-wear ring 48 and the sealing ring 49 are all set on the piston sleeve 46. The nut 50 is set on the second connector 40 and is threadedly connected to the threaded part 29 on the second connector 40.

[0048] After the piston rod 12 is moved out of the cylinder 1, the control board 7 controls the extension of the second electric push rod 41, causing the crossbar 42, which is fixedly connected to the second electric push rod 41, to move towards the connector. This causes the mating block 43 on the crossbar 42 to also move towards the connector. Simultaneously, the mating block 43, through its engagement with the wedge block 37, slides into the second sliding hole 39 until the mating block 43 passes through the second sliding hole 39 near the surface of the second electric push rod 41. At this point, the second electric push rod 41 stops extending. The second connector 40 can be pulled out in the opposite direction of the piston rod 12 to disassemble the first connector 33 and the second connector 40. After removing the second connector 40 from the first connector 33, the nut 50 can be unscrewed from the second connector 40 to remove the piston sleeve 46 and the buffer sleeve 45. Then, the anti-fouling ring 47, the anti-wear ring 48, and the sealing ring 49 can be removed from the piston sleeve 46. Compared with the current disassembly of hydraulic cylinders, this hydraulic cylinder greatly facilitates the disassembly of the operator, thereby reducing the disassembly difficulty to a certain extent.

[0049] Working principle: When the cylinder needs to be disassembled, the main control board 7 controls the first electric push rod 15 to start, so that the push plate 16, which is fixedly connected to the first electric push rod 15, pushes the first magnetic block 17 to move towards the baffle 20, and pushes the baffle 20, which is fixedly connected to the second magnetic block 21, to move. When the surface of the second magnetic block 21 approaches the first magnetic block 17 and is flush with the surface of the locking block 18, the first spring 19 releases the stored elastic potential energy, thereby pushing the locking block 18 to move and slide out of the sliding groove 5, thereby causing the cylinder head 9 to separate from the cylinder barrel 1.

[0050] When it is necessary to fix the cylinder head 9 to the cylinder barrel 1, the locking block 18 is inserted into the sliding groove 5 through the insertion hole 10 on the cylinder head 9. During the process of the locking block 18 being inserted into the sliding groove 5, the first spring 19 stores elastic potential energy to facilitate the subsequent separation of the cylinder head 9 from the cylinder barrel 1. During the movement of the locking block 18, when the first magnetic block 17 and the second magnetic block 21 correspond, the second magnetic block 21 attracts the first magnetic block 17, causing the first magnetic block 17 to move towards the inner groove 4. At the same time, the main board 7 controls the first electric push rod 15 to retract, so that the first magnetic block 17, which is attracted to the second magnetic block 21, is inserted into the inner groove 4. At this time, the cylinder head 9 is fixed to the cylinder barrel 1.

[0051] The cylinder is equipped with a locking mechanism, which makes it easy to fix the cylinder head 9 to the cylinder barrel 1. When disassembly is required, it is also easy to remove the cylinder head 9 from the cylinder barrel 1. Compared with the current connection method of cylinder head 9 and cylinder barrel 1, this device makes it easier for operators to disassemble cylinder barrel 1 and cylinder head 9.

[0052] After removing the cylinder head 9 and cylinder 1, the control board 7 controls the drive motor 25 to start, causing the drive rod 26, which is fixedly connected to the output end of the drive motor 25, to rotate. Through the threaded transmission of the trapezoidal block 27 and the threaded part 29 on the drive rod 26, the trapezoidal block 27 slides on the drive rod 26. Through the cooperation of the trapezoidal block 27 and the pop-out block 30, the pop-out block 30 partially slides out of the first sliding hole 23, so that the pop-out block 30 sliding out of the first sliding hole 23 abuts against the main sealing sleeve 11. The operator can remove the main sealing sleeve 11 inside the cylinder 1 by pulling out the piston rod 12. With the drive mechanism, the operator can pull out the main sealing sleeve 11 at the same time as pulling out the piston rod 12, which makes it easier for the operator to disassemble the main sealing sleeve 11 inside the cylinder 1.

[0053] After the piston rod 12 is moved out of the cylinder 1, the control board 7 controls the extension of the second electric push rod 41, causing the crossbar 42, which is fixedly connected to the second electric push rod 41, to move towards the connector. This causes the mating block 43 on the crossbar 42 to also move towards the connector. Simultaneously, the mating block 43, through its engagement with the wedge block 37, slides into the second sliding hole 39 until the mating block 43 passes through the second sliding hole 39 near the surface of the second electric push rod 41. At this point, the second electric push rod 41 stops extending. The second connector 40 can be pulled out in the opposite direction of the piston rod 12 to disassemble the first connector 33 and the second connector 40. After removing the second connector 40 from the first connector 33, the nut 50 can be unscrewed from the second connector 40 to remove the piston sleeve 46 and the buffer sleeve 45. Then, the anti-fouling ring 47, the anti-wear ring 48, and the sealing ring 49 can be removed from the piston sleeve 46. Compared with the current disassembly of hydraulic cylinders, this hydraulic cylinder greatly facilitates the disassembly of the operator, thereby reducing the disassembly difficulty to a certain extent.
